And has lived to tell about it?

Did you notice a significant decrease in vibration? Was it worth the effort?

My isos are about 9 years old and my 850 vibrates all the way up to 4000rpm until it smooths out and my adjusters have plenty of play.
I think I was sold at that time, the harder rubber ones.

Mine are not worn out, but I am tired of the vibration.

Anyone who converted from hard to "soft" have any positive comments?
thanks
